Not worthy because it was speared? C'mon I know this is a fishing board, but being that I do both, I can say it's MUCH harder to spear a flattie than to catch on a line. Spearfishing for them you are just outside of or in the surf a lot of the time, visibility sucks, you typically see the tail of a flattie flapping in your peripheral vision as it flies away because it saw you first. I'd say you actually get to take a shot at one 1 in 100 times you see one. On top of that, out of the shots you take, you probably will only land a few.

The record for spearfishing a California halibut is 72.5 lb. I believe it was from Santa Cruz Island, but possibly Santa Rosa.
